Notes:
1.  Test conditions and output loading conditions are specified in the AC Test Conditions and AC Test Loads (Figure 1).
2.  Tested with the load in Figure 2.Transition is measured ±500 mV from steady-state voltage. Not 100% tested.
3.  The internal write time is defined by the overlap of CE LOW and WE LOW.All signals must be in valid states to initiate a
Write, but any one can go inactive to terminate the Write.The Data Input Setup and Hold timing are referenced to the rising
or falling edge of the signal that terminates the write. Shaded area product in development
